As diagnostic ports vary greatly across the spread of coach-builds and years, the pinning and socket types vary significantly. When you call we will ask for your coachs' make, model and yer as well as what type of Diagnostic socket(s) you have. This may require a close look, first, to determine the physical nature of the socket, number of pins available and those used in that socket. Refer to the document, SilverLeaf Electronics J1708/J1587, J1939, RV-C Wiring Diagrams to identify what the Diagnostic sockets look like. Its regretful that, for this reason alone, we're not able to have an online store.

To start a fresh installation, download the latest "Distribution Disk," below. However, when first prompted, Open it (don't download it) --save/copy the Folder it contains to a place on your PC you can find easily, such as c:\ or your Desktop.

Install the drivers by Opening 'Install_Drivers.exe' Once the driver Software has completed, Install program from that same folder (ex: "Distribution_Disk_v4.0.x"). Reboot, open the VMSpc program with that new desktop shortcut, select your specific engine (when prompted). The first time opening you'll need to confirm that communications are set; USB JIB etc. Follow the manual on this--not too difficult. Need a hand? Call and we can walk you through.
